Rhinestone Encrusted Circular Brooch or Pendant

The item prominently displayed in the foreground is a circular brooch or pendant, crafted with numerous clear, faceted rhinestones. It appears to be made of a silver-toned metal, possibly a base metal alloy, given the context of costume jewelry often featuring such materials. The rhinestones are uniformly set around the perimeter of the circular form, creating a glittering effect. Each stone is small and appears to be individually prong-set or bezel-set, though the intricate detail is slightly blurred. The construction suggests a solid, rigid form, not flexible. There are no immediately visible maker's marks or stamps within the cropped image. The overall condition appears to be relatively good, with no obvious missing stones or significant discoloration of the metal. The sparkle suggests the rhinestones are clean and retain their brilliance. Based on its design and common materials, this piece likely dates from the mid-20th century, possibly 1950s-1980s, a period known for popularizing elaborate rhinestone jewelry. Its quality is typical of mass-produced costume jewelry, designed for aesthetic appeal rather than intrinsic material value, but it demonstrates careful craftsmanship in the stone setting. In the background, other pieces of jewelry are visible, including a silver-toned necklace or bracelet adorned with small pearls and clear stones, and another wider, textured metal bangle or bracelet, further indicating a collection of similar costume pieces.
